<p><P>PROBLEM TO BE SOLVED: To provide a variable capacity turbine capable of preventing a turbine wheel from being damaged by nozzle wake resonance and a variable capacity turbocharger equipped with the variable capacity turbine. <P>SOLUTION: The variable capacity turbine 100 has a variable nozzle 20 attached to a nozzle rotation shaft 24 at a fluid inlet flow-path to the turbine wheel which is rotatably driven and changes flow rate of the fluid for flowing into the turbine wheel by rotating the variable nozzle 20 around a shaft of the nozzle rotation shaft 24 with a nozzle driving means to change a blade angle of the variable nozzle. In the variable capacity turbine 100, at least one groove 101 is provided in a peripheral direction on a wall part 25 for forming the fluid inlet flow-path. <P>COPYRIGHT: (C)2004,JPO</p> |
